mtPaint is a simple painting software developed from scratch so you can easily create pixel art and manipulate digital photos.

It uses the GTK+ toolkit (version 1 or 2) and runs on PC's via the GNU/Linux or Windows operating systems. Because of its simplicity it can also run on older PC hardware (e.g. a 200MHz CPU and 32MB of RAM).

By default it is in the English language, but there are also translations available for other languages such as Spanish, Czech, French, Portuguese and Brazilian Portuguese.

PhotoEdit is a powerful photo editor, its source code is available, it can read, write, and manipulate an image in many image formats (over 38 major formats) including popular formats like TIFF, JPEG, PNG, PCD, PIC, PSD, and GIF.
